nanostores

Core library is under 1KB (271-802 bytes minified and brotlied) with zero dependencies, as emphasized in the README, making it ideal for performance-sensitive bundles.

Works seamlessly with React, Vue, Svelte, Solid, and others via dedicated integration packages, allowing consistent state management across multi-framework projects.

Uses atomic stores that only include used stores in each code chunk, reducing bundle size through efficient dead code elimination.

Supports mount/disabled modes to conserve resources (e.g., network connections) when stores aren't actively used, a unique feature highlighted in the guide.

Provides good TypeScript support with helpers like StoreValue for type-safe state, encouraging robust development practices.
